A detachment device of the engine oil filter of an automobile includes a base, two toggle plates, two clamping plates, and two link mechanisms. The clamping plates are connected by the link mechanisms which cannot be returned automatically, so that the user needs not to exert a large force to pull and push the two clamping plates, thereby facilitating the user's operation. In addition, each connecting portion has a width different from the diameter of the base, thereby forming a gap between the base and each connecting portion, so that the user can clearly watch the present position of the engine oil filter, thereby facilitating the user mounting and detaching the engine oil filter.
